§ The result
Factorial leads Zappyhire by 12 points.
Factorial sits 12 points above Zappyhire under rubric v1.0 — 46 against 34 — with Factorial filed under ATS-integrated and Zappyhire under Screening. Factorial leads 6 of the 7 criteria, including Article 11 Technical Documentation, while Zappyhire leads 1, including Bias Audit Transparency. The advantage Factorial holds is spread out: Article 11 Technical Documentation is both the widest raw gap and the heaviest weighted swing (Factorial 52, Zappyhire 30, 20% weight), yet it supplies only 35% of the weighted points Factorial gains across the 6 criteria it leads.
